METHOD OF PROTECTION OF METAL HEATING ELECTRODES OF MELTING FURNACES BY DC CURRENT |
| 摘要 |
<p>Metal heating electrodes of melting furnaces are protected against reduction of ions from a silicate melt by superposition of DC current on the AC heating current and by forming and maintaining on these electrodes a passivation layer with a higher electric specific resistance than the resistance of the melt.</p> |
